I don't think OP said that he was guilting her into sex, only that he was upset/uneasy. Blue balls can make people feel that. Provided he didn't guilt or complain, it's perfectly normal to feel "uneasy" (And walk to the bathroom). It all depends really on what he said / did.
Don't cry, don't regret and don't blame
Weak find the whip, willing find freedom
Towards the sun, carry your name
In warm hands you are given
Ask the wind for the way
Uncertainty's gone, your path will unravel
Accept all as it is and do not blame
God or the Devil
